Postman

Postman is primarily an API development platform, which aligns with the concept's focus on connecting to various data sources and APIs. It offers extensive API and database integrations, allows for code customization through scripting and testing, and has introduced workflow automation features (Flows) and AI/LLM integrations (Postbot, AI Agent Builder). While it doesn't explicitly offer a drag-and-drop UI builder for general internal tools, its 'Flows' feature provides a visual canvas for workflow automation. Security and hosting options are also present. The core difference is that Postman is focused on API lifecycle management, not general internal tool building with a rich UI component library like Retool.
